Specification of Letters Patent.

Patented July 6, 1909.

Application filed October 14, 1908. Serial No. 457,609.

To all whom it may concern:

Be it known that I, HARRY S. SWAN, a citizen of the United States,residing at Wanamingo, in the county of Minnesota, have invented certainnew and useful Improvements in Means for Detachably ConnectingWagon-Boxes and Racks; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention has for its object to provide a convenient and reliablemeans for detachably connecting together a wagon body and a rack; and tothese ends, my invention consists of the novel devices and combinationsof devices hereinafter described and defined in the claim.

The invention is illustrated in the accompanying drawings wherein likereferences refer to like parts throughout the several VIEWS.

In said drawings; Figure 1 is a plan view showing the wagon body andrack tightly clamped together in working position. Fig. 2 is a detail insection on the llne r of Fig. 1. Fig. 3 is a section on the line a 0: ofFig. 2. Fig. 4 is a detail in section on the line .12 r of Fig. 1; andFig. 5 is a plan view of one of the joint plates for interlocking thewagon body and rack, detached.

The numeral 1 designates a wagon body of the proper strength and heightto support the rack 2 above the level of the wagon wheels, when the saidparts are in working position on the running gear of a wagon, not shown.The rack 2 is of the customary skeleton form, and all its cross bars areprovided on their under sides with mortise-like plates 3 adapted toengage with the to portions of the sides of the wagon-box 1 w en therack is properly located on the body, as shown in Fig. 1. The front andrear members of the rack cross bars are shown as provided with clevises4 which embrace the said cross bars and are carried thereby, withfreedom for vertical sliding motion relative thereto under the action ofeccentric headed cam levers 5 which are carried by the upper ends of theclevises 4 in such position that the of Goodhue and State 1 I eccentricheads of these levers 5 will react against the top surfaces of the crossbars for raising or lowering the clevises 4, as best shown in Fig. 2.The sides of the wagon t body 1 are provided with hook-ended lugs 6secured thereto in proper position to be engaged by the lower ends ofthe clevises 4 when the latter are in their lowermost position andadapted to be tightly clamped thereto when the cam levers 5 have beenturned into proper position to draw the clevises 4 to their highestpoints,

in Fig. 2.

It is obvious that the parts marked 4, 5 and 6 constitute a form ofclamp; and that the four sets of these clamps applied at the corner'o'ints between the wagon body 1 and v the rac 2, when the latter isproperly seated 1 thereon, will firmly and securely clamp the rack tothe wagon body in its proper working position. The mortise plates 3 arebolted or otherwise rigidly secured to the cross bars of t the rack 2,and the hook lugs 6 are bolted or otherwise rigidly secured to the sidesof the wagon body 1.

The rack is, of course, adapted for use in the customary way for haulinghay, straw, or other similar material, when loaded thereon.

What I claim is:

The combination with a wagon box, of a rack having mortise-like plateson the under side of its cross bars adapted to engage with. the topportion of the sides of the wagon box, a series of hook-like lugs on thewagon box,

a series of links carried by the cross bars of the rack and mounted forvertical movement in seats formed in said plates and adapted to engagesaid lugs, and which links are provided with a series of cam leversadapted to react against the upper face of the rack cross bars fordetachably clamping said box and rack tightly together, substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.

HARRY S. SWAN.
